Title: Oscillating drive for sieves - has different angles produced between radii of oscillators for each phase of operation
Inventor: WOROFSKY HERBERT
IPC: B06B3/00
Filed: 1973-10-23
Abstract: Oscillating drive for sieves which allows the initial revolution rate of one oscillator to be altered or the revolution speeds to be changed during the running has two countercurrent, self-synchronising circular oscillators which produce linear movement. Different angles between the radii are produced in each phase of the operation and the imbalance points of the oscillators and the connection line between the swivel axes lie on the radii. The different angles are produced by making the initial revolution of the oscillators different before the self-synchronising, when the oscillators' are viewed individually.
